Jacksum: Easy checksum utility
Calculate and verify checksums for files with Jacksum, a simple and easy-to-use software that supports multiple algorithms, including MD5, SHA-1, CRC32, and more.
What is Jacksum?
Jacksum is an open source checksum utility written in Java that can calculate and verify various checksum algorithms for files. Some of the supported checksum algorithms include:
- MD5
- SHA-1
- SHA-256
- SHA-384
- SHA-512
- CRC32
- Adler32
- Fletcher16
- Fletcher32
- and more
It has a simple graphical user interface for easy usage, where you can add files or folders recursively to generate checksums. There are options to export the checksum results to a text, HTML, XML or CSV file.
Jacksum can also be used from the command line interface which allows for batch processing and scripting. It can read checksums from and export checksums to files.
Some use cases for Jacksum include:
- Verifying downloaded files against published checksums
- Ensuring integrity of backup archives
